Modules in demand: PV companies in the region are busy.
However, demand has calmed down somewhat compared to the previous year.

Solar energy is booming more than ever: Almost 2,000 new PV systems were installed on roofs in the Starnberg district in 2023 - the number has increased by 42 percent compared to the previous year.
The potential is still huge: an estimated 80 percent of suitable roofs are still unused.
District - Better a small photovoltaic system than none at all: This belief seems to have prevailed in the Starnberg district last year.
The number of systems increased by 42 percent compared to 2022, while their possible output “only” increased by 26 percent.
In total, almost 2,000 new examples were installed on roofs, bringing the total number to around 6,550 - a jump that has never been seen before in the Five Lakes Region.
And yet there is still a hell of a lot of potential, as district office spokesman Stefan Diebl says in response to Merkur's query: "We are assuming that there are probably 80 percent of suitable roof areas that are not yet equipped with PV systems." This is an estimate.
If you want to know how suitable your own roof is, you can find out more in the district's solar cadastre at www.lk-starnberg.de/solarkataster.
“This gives homeowners a simple initial assessment of how much sun actually shines on the roof throughout the year and which area is best suited,” says Diebl.
A planning and profitability calculator is also included.
Systems on roofs make up 75 percent of the PV share
Small livestock also make a mess: the systems on the roofs make up 75 percent of the PV share (the 531 balcony power plants registered in the district account for 0.4 percent).
But how large systems can catapult overall performance in the region can also be clearly seen in the numbers.
From 2021 to 2022, the so-called installed, i.e. maximum possible, output (kilowatt peak) rose sharply (according to the district office, the network operators only provided information on yield, i.e. annual kilowatt hours, in May).
The reason: the largest open-space facility in the district on the motorway near Geisenbrunn, which went into operation in September 2022.
Energy consultant Ingo Martin, managing director of the Gauting-based company Adsol, has a plausible explanation for the solar boom on roofs: “Russia's war of aggression on Ukraine has given the PV market a special boom.” He points to high electricity prices and the current concern about one Gas emergency.
“This mountain of orders has now been processed, so that orders are currently being installed eight weeks after receipt of the order.” Christian Weiderer from AC Solar in Starnberg confirms: “In 2023 the demand was extreme, we just had to turn people down.” The business has now settled down normal, constant level.
Dealer: Prices for PV systems have calmed down
Prices have also calmed down, says Ingo Martin.
The goods are sufficiently available again.
It is important to his customers to have a long-term service partner in the region and a backup power supply in an emergency.
And: “Basically, e-mobility and heat pumps are now considered at the same time when purchasing,” says the energy consultant.
The truth behind the solar boom is: The share of renewable energies in electricity consumption in the district was still only around 23 percent in 2023 - Bavaria averaged almost 60 percent.
Why is it that so many roofs are still module-free?
Christian Weiderer confirms that sole owners find it easier to make the decision.
In residential buildings with owner associations and several tenants, there are logically different interests.
Weiderer and his colleague Martin find that too much and sometimes incorrect information from politics and the media has a confusing and deterrent effect on potential interested parties.
One consolation: Incidentally, the four Berger wind turbines have had their most profitable year ever (we reported).
A few more facilities are being planned.
And this also applies to ground-mounted PV systems - see Pöcking, for example, where the planned solar park on the edge of the barracks could quadruple the share of renewable energies in the community.
